Timisoara is a growing city in the western part of Romania, in a seismic area, with a lot of masonry buildings with historical and cultural value, with interesting structural elements such as vaults, arches, slabs, walls, that were affected by earthquakes, subsidence of foundations, negative human actions or lack of interventions. Masonry historical structures in Banat seismic area present particular failure mechanisms, so there is a need for new, modern, fast, easy-to-apply and reversible consolidation methods. With this type of methods is possible to assure the local and global resistance, ductility, stability and rigidity for historical buildings. This article shows the consolidation methods that were applied on the buildings Sf. Gheorghe 3 and 4, in the historical centre of Timisoara, on masonry structures with historical value. The solutions that were applied are using new, innovative fibre-reinforced composite materials, in order to repair the existing damages and prevent further ones. The consolidation solutions with these new composite materials reduce the buildings vulnerability and present the advantage of being fast and easy to be executed.

Extreme actions represent a high risk for buildings belonging to historic urban areas and archaeological sites. Because of the conformation of the buildings, the low quality of used materials and the current state of conservation, these buildings tend to be very vulnerable to horizontal forces generated during earthquakes and terrorist attacks. This article analyses the mechanisms caused by extreme actions that are capable to generate a considerable degree of damage or even collapse of international cultural heritage buildings from historic urban centers and sites.

Romania is a country divided in two important seismic areas, with a history that has as proof buildings with historical and cultural value, most of them made in masonry. A large number of those buildings have suffered damages because of earthquakes, subsidence of foundations or lack of interventions. In this article will be presented some consolidation methods applied on masonry buildings in Romania, with composite fiber-reinforced materials, made by Kerakoll producer. Those modern consolidation solutions that were used in Romania may represent examples that can represent the base of choosing the consolidation methods for other buildings with similar damages.
